Definitions
- the invention relates to a shoe sole with integrated anti-slipping elements which can be adjusted between an inactive position and an active position by means of a central actuation unit.
- the invention is furthermore directed to all types of shoes which are provided with such a shoe sole with integrated anti-slipping elements.
- Shoe soles with integrated anti-slipping elements which can be adjusted between a non-active position, i.e. a position set back with respect to the tread, and an extended and thus active position are known in different embodiments.
- anti-slipping elements which in particular have the form of spikes, are respectively supported in individual functional units and are axially adjustable between their active and inactive positions through rotation by the central actuation unit via at least one flexible drive element.
- each functional unit includes a housing in the form of a shallow pot in which a rotatably supported drive disk is provided which cooperates with a respective flexible drive element and either has a central extension or neck which engages into a central recess of the anti-slipping element while forming a rotationally fixed coupling which ensures an axial relative displacement, said anti-slipping element cooperating via radially projecting guide cams with a spiral ramp fixed to the housing, or has, instead of the central extension two mutually diametrically opposed extensions or necks in the form of drive wings which extend perpendicular to the drive disk and engage at the radially projecting guide cams of the anti-slipping element.
- the drive wings cooperate with the guide cams via sloped surfaces deflecting rotary drive forces in the axial direction.
- the functional units can be realized with small volumes, ensure an easy motion in the adjustment of the anti-slipping elements due to the cooperation of the spiral ramp and the guide cams and avoid any need for force support by springs or the like.
- each functional unit which receives the actuation elements such as the drive disk and the anti-slipping element is outwardly practically sealingly terminated, with it above all also being a contributory factor that the housing of the functional unit is surrounded by a plastic jacket which fixes the outer contour of this functional unit and which is realized in an injection molding process.
- a further particular advantage of the embodiment in accordance with the invention consists of the fact that the cooperating surfaces of the spiral ramp and the guide cams extend at least substantially perpendicular to the axis of rotation of the anti-slipping element and form support surfaces between the anti-slipping element and the housing which are in particular metallic and are free of transverse, force components in the active extended position of the anti-slipping element.
- the support surfaces are preferably disposed in a type of undercut which ensures, on the'one hand, that the extension position is also clearly mechanically defined and, on the other hand, that a problem-free retraction from this extended position into the inactive position is possible.
- the part of the anti-slipping element provided for the outward projection can also be designed as a replaceable part so that the part exposed to wear can be changed independently of the adjustment mechanism or, optionally, different elements can be used in dependence on the respective field of application.
- connection between the central actuation unit and the individual functional units via flexible guide passages which accept threaded spindles, belts or wires extending from the central actuation unit to the respective functional units and ensure their guidance with an easy motion and a low friction is likewise of particular advantage.
- These guide passages are preferably designed in the form of two plastic passages substantially of more U shape which can be coupled to one another.
- a particularly easy motion and a secure operation of the total arrangement is also achieved in accordance with the invention in that not all the functional units are connected in series with respect to the control drives of the spindle, the wire or the belt, but that rather a group of functional units, driven by the same actuation unit, for example, are combined in the front sole region and a group of functional units are combined in the heel region, with only the units within the same group being driven in series, but with a parallel connection of the drive being present with respect to the units in the front sole region and in the heel region.
- FIG. 1 a perspectively represented side view of a sports shoe in accordance with the invention with extensible anti-slipping elements
- FIG. 2 a perspective oblique view of an embodiment of a shoe sole in accordance with the invention
- FIG. 3 a perspective representation of functional units connected to one another via guide passages and with an associated cover unit before the integration into the respective sole;
- FIG. 4 a detail of the drive unit provided for the actuation of the anti-slipping elements with a pivotable actuation grip
- FIG. 5 a perspective detailed view of the heel-side region with functional units and actuation unit
- FIG. 6 a sectioned representation of a functional unit for the explanation of the detailed structure
- FIG. 8 a perspective, partly sectioned representation of the functional unit in accordance with FIG. 7 ;
- FIG. 3 shows, in a perspective representation, an example for a total system which can be integrated into the respective shoe sole 1 after joining together of the two units shown and which in each case represents a completely assembled functional unit which can be brought into the shape provided for the injection molding of the sole, can be suitably positioned and can then be overmolded with the sole material.
- This total system includes a number of functional units 3 which can be preset in the individual case in accordance with the given demands and with which in each case an extensible anti-slipping element 4 is associated.
- Each functional unit 3 includes a housing 7 which has approximately the shape of a shallow pot, which is closed on the side disposed opposite the anti-slipping element 4 by means of a support cover 18 and whose design will be explained in detail later.
- the different components of the functional unit 3 are joined together on the assembly and are then enclosed in a plastic jacket within the framework of an injection molding process, with the respective unit 3 then being closed by a support cover 18 which is fixed by clamping bolts or rivet bolts 19 .
- the individual functional units 3 are connected to one another and to a central actuation unit 5 via guide passages 15 in which the wires or belts run by means of which the anti-slipping elements 4 are switched between the active and inactive positions via the actuation unit 5 .
- the guide passages 15 consist of plastic and are in particular made flexible in a preset manner such that the total system of functional units and guide passages does not disturbingly impair the bending properties of the respective sole.
- the guide passages 15 preferably merge tangentially into the respective functional units 3 so that the drive wires can be guided tangentially to a drive disk 8 provided in each functional unit 3 .
- the jacket of the housing 7 of the functional units 3 , the U-shaped guide passages 15 , the deflection units 16 and the bearing shell 14 for the actuation unit 5 consist of a one-part injection molded plastic part, with the components of the functional units 3 being positioned in the required manner in a corresponding mold on the injection of this part and being overmolded while forming the respective overall housing 7 .
- the cover unit 17 which is shaped complementary to the basic structure can be applied and the total arrangement can thus be moved into the closed state.
- a guided plugging together with a simultaneous clipping preferably takes place between the two units.
- a prefabricated, fully functional units is then available which is actuable via the drive bar 21 and which can be integrated into the respectively provided sole by an overmolding procedure.
- FIG. 4 shows the flexible drive bar which is associated with the roll 13 and whose coupling end 22 can be introduced into the roll and can be fixedly connected to the roll.
- the flexible drive bar 21 which is integrated into the sole material, has a pivot bearing 23 at its free, outwardly disposed end and an actuation grip 24 is hinged to said pivot bearing.
- Two latch positions 20 are associated with this actuation grip 24 or with its pivot bearing 23 , with the position shown in the drawing corresponding to the position pivoted away in which—as indicated in FIG. 1 —a rotation of the drive bar is possible.
- the second latch position corresponds to the contact position at the respective shoe to which the actuation grip 24 can be matched in a shape matched manner.
- FIG. 5 shows, in a perspective detailed view, the cooperation of the actuation unit 5 with the associated functional units 3 , which can also be termed spike domes.
- the cover unit 17 as is shown in FIG. 3 , has not yet been applied to the guide passages 15 or the functional units 3 and the actuation unit 5 in the representation of FIG. 5 .
- Any suitable device can generally be used for the rotation of the drive roll 13 , with at least in principle an electric, controllable drive also not being precluded provided that it is available in a corresponding compactness.
- FIG. 6 shows the inner structure of a functional unit 3 .
- the drive disk 8 is guided axially and radially with an easy motion between an outer closure disk or support disk 18 and an inner support disk 25 , with the spacing between these two support disks 18 , 25 being preset by a housing spacer region 29 .
- the axial guidance of the drive disk 8 is achieved by the support disks 18 and 25 and these support disks 18 and 25 also ensure the radial guidance via a cylindrical guide neck 31 or a ring neck 30 which are formed at the drive disk 8 .
- the drive disk 8 furthermore has a central extension or neck 9 which engages into a central recess 10 of the anti-slipping element 4 while forming a rotationally fixed coupling which ensures a relative axial displacement.
- the central extension is preferably provided with an external toothed arrangement 27 which engages into complementary shaped recesses in the anti-slipping element 4 . This relative engagement takes place with clearance so that the relative axial movability between the central extension 9 and the anti-slipping element 4 is always ensured.
- the housing 7 has a spiral ramp 12 at the inside which surrounds the anti-slipping element 4 and which cooperates with in particular two mutually diametrically opposed guide cams 11 which are made in one piece with the anti-slipping element 4 .
- Each rotation of the drive disk 8 accordingly results in a corresponding rotation of the anti-slipping element 4 around its axis 34 and, at the same time, with every rotation, the guide cams 11 slide on the spiral ramp 12 and thus move the anti-slipping element 4 in dependence on the direction of rotation between the active extended position and the inactive retracted position in which the inwardly disposed end of the anti-slipping element 4 moves into the housing recess 33 .
- the housing optionally has a closure cover 28 , which is held by the housing 7 , at the side of the exiting of the anti-slipping element 4 from the functional unit 3 . If no such closure cover is provided, the housing 7 is in any case closed by a jacket wall 34 on the base side while leaving free the exit opening for the anti-slipping element 4 so that no foreign substances can penetrate into the housing, but so that the extension and retraction of the anti-slipping element 4 is not hindered.
- all the functional units 3 do not necessarily have to be connected in series drive-wise, but that preferably at least two drive groups are formed for the functional units 3 and can be controlled via the common actuation unit 5 .
- the functional units 3 are preferably combined to form part systems in the heel part, on the one hand, and in the front sole part, on the other hand, with the drive disks 8 of the functional units being connected in series in each part system, but the parts systems themselves being connected in parallel drive-wise.
- the system in accordance with the invention can be realized in a very space saving manner, with the total height of the functional units 3 being able to be disposed, for example, in the range from 10 to 13 mm and the height of the flexible guide passages 15 being able to amount to approximately 4 to 6 mm, for example.
- the same plastic is preferably used in each case for the realization of the housing 7 , of the guide passages 15 and for the associated support of the actuation unit.
- each support disk 8 has an actuation slot 25 for the rotational positioning of the support disks, in particular on assembly.
- each support disk 8 is provided with a wire clamping arrangement 36 .
- FIG. 7 shows a further particularly preferred embodiment of a functional unit 3 , with the main components being shown perspectively in the manner of an exploded representation.
- a drive disk 8 is rotatably supported in a housing 7 of the shape of a shallow pot which is completed by a lower housing cover part 42 , analog to the embodiment of FIG. 6 .
- This drive disk 8 has two mutually diametrically opposed extensions in the form of drive wings 37 , 38 . These drive wings 37 , 38 also serve for the axial support of the drive disk 8 , since the drive disk 8 is guided via these wings 37 , 38 between the closure support cover 18 and a support disk 25 which is arranged in the lower housing cover part 42 .
- the drive wings 37 , 38 cooperate with the guide cams 11 projecting radially from the anti-slipping element 4 in a manner such that, on a rotary movement of the drive disk 8 , the drive wings 37 , 38 move the guide cams 11 over the spiral ram 12 formed in the housing 7 between the two end positions, namely the retraced and extended positions of the anti-slipping elements 4 .
- the perspective representation of the functional unit with the components in accordance with FIG. 7 in the perspective representation in accordance with FIG. 8 allows it to be recognized that the individual components can be assembled very easily to form the finished functional unit since essentially only a plugging together of the individual elements with a subsequent riveting or pressing together of clamping bolts 19 has to take place.
- the anti-slipping element is as a rule made in two parts, with the inner part ensuring the actuation and made as a hollow part for the saving of weight preferably being adhesively bonded to the outer part consisting of hard metal.
- the threaded spindles 41 are—which is not shown in FIG. 9 for reasons of simplicity—substantially guided over their total length in corresponding passages, which in particular also applies to the region of the functional units in which each drive disk 8 carries a toothed arrangement adapted to the threaded spindle 41 at the outer periphery of said drive disk so that a rotation of the drive disk 8 takes place in dependence on the respective longitudinal displacement of the threaded spindle 41 and an extension or retraction of the anti-slipping elements thus takes place in the respective functional units 3 in the manner already described.
- a plurality of drive disks 8 can also be driven by each spindle in the embodiment of the drive of FIG. 9 , in a corresponding manner to how this was already described in connection with the control wire drives, i.e. groups can be formed whose individual functional units can each be positioned in the desired region of the shoe sole.
- the shoe sole in accordance with the invention can basically be used in conjunction with every type of shoe. Sports shoes, hiking boots, trekking boots, golf shoes and the like can preferably be provided with a sole in accordance with the invention. In every case, the utility value and practical value of the respective shoes are improved and the safety for the user is above all increased.
